Borinquen Apartments is the complete renovation of two prominent apartment buildings with street level commercial spaces located along Main Street in Springfield, MA. Built between 1906 and 1924, one of the buildings received historic tax credits for renovations. Successfully overcoming the challenge of limited area for staging, the renovations were phased and undertaken in stacks of vacant units. Davis Square Architects removed lead and underground oil storage tanks, replaced exterior porches and egress stairs, provided extensive building envelope renovations, renovated the interiors, converted the heating system to centralized high-efficiency gas-fired boilers, and added new life safety and security systems. Additionally, the existing commercial spaces were converted into a laundry facility and office space for property management.
